To all:
I am following angiogenesis (positive and negative approach) for the last few years. Scios is company which is heavily involved in *therapeutic angiogenesis* (bFGF, VEGF124), so it was in my screen for some time. Several weeks ago initiated position and bought few Apr. calls. At this time my position is based on expectation that Natrecor AC meeting in January will have positive outcome, but also am looking far beyond this point.
Do not remember that anyone posted report from Florida (Heart Failure Society) on neseritide (Natrecor) PIII safety trial:

Cardiac Hormone Studies Show Clinical and Cost-Effectiveness Advantages for Treatment of Acute CHF
Data Presented at Second Annual Heart Failure Society of America Meeting
BOCA RATON, Fla., Sept. 16 /PRNewswire/ -- At scientific sessions today, investigators presented data on the genetically-engineered version of the cardiac hormone BNP (b-type natriuretic peptide) known as nesiritide. In separate presentations, investigators reported that clinical study data comparing the effect of nesiritide to dobutamine in patients hospitalized with acute congestive heart failure (CHF) showed that treatment with nesiritide was associated with a lower incidence of dangerous cardiac arrhythmias and a shortened course of intravenous therapy.
The studies were presented today at the second annual scientific meeting of the Heart Failure Society of America by Marc Silver, M.D., Director, Heart Failure Institute, Christ Hospital Medical Center, Oaklawn, IL, and Andrew Burger, M.D., Beth Israel Deaconess Medical Center, Boston, MA.
Dr. Silver's study, evaluating outcomes of hospitalized patients with acute CHF receiving either nesiritide or the commonly-used inotrope dobutamine, found that in patients treated with nesiritide, intravenous administration could be discontinued as much as one to two days earlier than in patients treated with dobutamine. Once released from the hospital, patients receiving dobutamine were also readmitted for CHF three times as often as patients receiving nesiritide (13 percent of dobutamine patients versus four percent of nesiritide patients).
''Our study found that, compared to dobutamine, nesiritide decreased the likelihood that patients would be readmitted once released from the hospital,'' Dr. Silver said. ''This suggests that treating acute CHF patients with nesiritide may lead to lower healthcare utilization costs than we see with dobutamine.''
The study reported by Dr. Burger evaluated the frequency of cardiac arrhythmias associated with nesiritide and dobutamine. Dobutamine was associated with more ventricular tachycardia (22 versus eight percent of patients) and cardiac arrest (five versus zero percent of patients) than nesiritide (0.03 ug/kg/min).
Dr. Silver noted that dose-related decreases in blood pressure, an extension of nesiritide's effect as a vasodilator, were seen in the trials but were manageable through dose reduction.
''It's clear that nesiritide will be a very important new member of the treatment-arsenal for patients admitted with acute congestive heart failure,'' said Dr. Silver. ''The next step is to evaluate how we may be able to use nesiritide to prevent patients from being admitted to the hospital in the first place.''
Nesiritide is a genetically-engineered form of the naturally-occurring hormone known as BNP (b-type natriuretic peptide), a hormone secreted by the ventricles of the heart as one of the body's natural responses to heart failure. It appears to help the body restore salt and water balance, and to improve the function of the heart. Dobutamine is an inotrope, a drug given to improve the heart's contractile function, frequently administered to individuals with acute CHF.
CONGESTIVE HEART FAILURE
Congestive heart failure (CHF) is a condition in which the heart can no longer pump enough blood to meet the needs of the body's other organs. This decreased pumping ability, and therefore reduced circulation, can have many consequences, such as: shortness of breath, tiredness, difficulty sleeping, swelling of the extremities, dry cough, and sudden weight gain (2-5 pounds in 1-4 days).
Congestive heart failure affects an estimated 4.9 million Americans, with nearly one million hospitalized with acute CHF each year. In 1998, Americans will spend an estimated $18.8 billion for the care of CHF patients in hospitals, doctors' offices, home care and nursing homes. Treatment for CHF accounts for more than five percent of the total health care costs in the United States each year.
The Heart Failure Society of America (HFSA) was established in 1995 and represents the first organized effort by heart failure experts from the Americas to provide a forum for medical personnel focused on congestive heart failure research and patient care.

Based on data from first efficiency Natrecor PIII trial, and this safety profile from second PIII trial (where Natrecor was administrated with current CHF drugs, doctors choice) compared with dobutamine (standard inotropic drug for acute CHF), I think that Natrecor chance to be recommended are very good.
However, my main interest is on FIBLAST (basic FGF) for coronary artery and peripheral vascular diseases and stroke. Was very disappointed after US PII/III stroke trials was halted.
Does anyone have more (specific) data about drug side effects in this trial? What type of side effects (or toxicity) related to drug they observed in this trial? Stroke is accompanied/caused with/by other diseases, so are this pts condition in trial entry reasons for observed toxicity?
